To tI/Z whom it may concern: Be it known that LAUGUsrE FRANoIsPOILLEVILLAIN DIT PAUL VILLAIN, a citizen of the Republic of-France,residing at Paris,A France, have invented certain new and use-y fulImprovements in Apparatus for Visibly and Audibly Indicating theSpjeedof Mot-or- Cars, Tram-Cars, and other Vehicles, of which vvMy inventionhas relation' to a device for be driven and for automatically indicatingwhen that speed isv exceeded, and in such arrangement of such a device.The principal object of my invention is to provide a speed-indicatingapparatus which maybe varied or adjusted toindicate the limit of speedat which the vehicle is to travel and which is combined withautomatically controlled means for indicating when the The natureandscope of myinvent'ionwill description, taken/in connection withtheacvcompanying drawings, forming partlhereof,

in which Figure 1 is a view, partlyinlvertical secratus embodyingmainfeatures of my inven-A tion. Fig. 2 is an enlarged horizontal sec-`tional view takenfon the line 2` 2'of Fig; l. Fig. 3 Vis an enlargedviewofthe incli-ne or cam governing the action of the beller audi-v blesignal, the curved cam or incline being projected on a dat surface andits ends sectioned; andFigs. 4 and 5v areenlarged horizontal sectionalviews: taken, respectively, on

Referring to the drawings, 1 represents the central weight of acentrifugal governor; 2,

mounted upon or fixed to the shaft, upon which the weight 1 isadapted'to vertically slide as the arms 2 expand or contractunder the inuence ofcentrifugal force. v The shaft 2 is lrotatedl'by means of miter'-gearing 4, which gearing et is set in motion by a pinion 5. The pinion5in turn is operated by the wheels or other rotating part ofthe vehicle,

(not shown,) so that themotion ofthe pinion is also elevated anddepressed as the weight 1 moves up or down onl thev shaft 3. A caseSincloses the governor and its accessories and serves also as a supportfor the lantern 9.

Referring now to Figs. 1 and 5, within the .frame of the lantern 9 ismounted a tubular vframe 9a, encircling the flame of the lantern,

and this frame carries three panels 9b, 9, and 9d, ofdierent-colored'glass-for instance, white, green, and red.A The tubularframe 9l is secured or fixed atv its top in a ring or crown 10, andpartly encircling thering or crown 10V is a sprocket-chain 11. y 11 alsopartly encircles a second rin gvor crown 13 keyed or otherwise securedto a sleeve 15.

Thechain This sleeve 15 is adapted to be turned by a hand-lever 16 andwhen soturned transmits" its movement through the'crown orgring 13,chain 11, and ring 10 tothe tubular Aframe 9, so as to i bringr any onepanel 9b, 9"', or 9d between the iiame and the lens of the lantern 9 toshow a color-white, green, 'or red-from the'lantern. In the drawings theintermediate color-panel 9C, whichis green, is shown, and this indicatesthe vintermediate speed of the yvehiclev for, say,`rural localities.white panel 9b--when turned in operative pos'ition indicates the lowestspeed of the vehi' cle for, say, city nlocalities, whereas the red panel9d when ldisplayed from ythe lantern 9 indicates topmost speed.` Thethree posi` tions ofthe hand-lever 1G, are secured by locking thehand-lever 16 to three 'points 17,

17h, andj17c, respectively, on a sector 17 by means of a pin 18.' Thesleeve 15 turns about a fixed rod or shaft 19, supported by the roof ofthe casing gong 20. p

` Referring now to Figs. 1 and 4, the handlever 16 carries at itsfulcral point 19 a platform 21, from which projects upward three panels21a, 21b,'and 21, the outer facesv of which correspond in color to thepanels 9b, 9,- and 9d-that'is to say, they are respectively white,green,and red. The movement of the The 8, and to the sleeve l5 is fixed a 'roohand-lever 16 to display a white, green, or red light from the lantern 9also turns the panels 21a, 2lb, and 21C within a casing 22,`

so as to display a correspondingly-colored panel from the opening 22e insaid casing 22d.

In the ring or crown 13 is formed an annular slot 2lbis to give passagefor a sleeve 22, fixed in the roof of the casing 8. In this sleeve 22 isadapted to rotate a spindle 23, carrying at its base within the casing Sa friction-disk 24. The spindle 23 also extends upward within the gong20 and carries at or near its upper end ahammer-lever 25, which when thespindle 23 rotates is adapted to strike the gong 20 to give an audiblesignal. On the top of the ring or crown 13 is fixed an incline or cam27, which is slotted in alinement with the slot 2lbis of ring 13. Uponthis incline or cam 27 rides a collar or nut 2G, interposedoetween thehammer-lever 25 and the incline or cam 27. When now the ring 13, withits cam or incline 27, is shifted by the hand-lever 16, the spindle willbe elevated or depressed as the collar or nut 26 rides up or down uponthe cam 27, and hence the disk 24, carried by said spindle 23, iselevated away from the disk G, traveling with the governor, or depressedtoward the said disk 6. It follows that if the lantern-panel is toindicate low or city speed and the colored panel 21L is likewise set thecam 27 is moved with the ring 13 so that the disk 24 is verynearthe disk6 of the governor. It then requires but a slight rise of thegovernor-weight 1 to cause the disk (j to frictonally engage the disk24, and thereby turn said disk 24 and spindle 23. As before explained,the turning or rotation ofthe spindle 23 causes the hammer 25 to strikethe gong 20, and henceaudiblyindicates an excessofspeed of the vehicle.In the same manner if green or country-road speed is indicated then theineline or cam 27is turned to a point where the spindle 23 and disk 24are elevated 1.o an intermediate position or that indicated in thedrawings. In this position the governor- Weight 1 and disk must rise afurther distance than in the former instance before the disk G touchesthe disk 24 to indicate through the rotation of the spindle 23 andhammer 25 an excess speed. If the light and the panels 2lC indicate redor maximum speed, then the incline or cam 27 preferably raises thespindle 23, so that the disk 24 is withdrawn from possible contact withthe disk 6that is to say, tho disk 24 is drawn upward to a plano abovethe lower end of anut orstop 30, which limits the upward movement of thedisk 6.

The operation of the device is as follows: The driver or operator of thevehicle irst moves the hand-lever 16 to set the proper panel 2l, 2lb, or2lc opposite the opening 22D in the casing 22d. This operation of thehand lever 16 moves the ring 13, which through the chain 1.1 operatesthe ring 10 to turn the proper panel 9b, 9C, or 9linto a positionbetween the iiame and the lens of the lantern 9. There is thus displayedat two points the proper color or visible signal, the panel 2l,

22h, or 22c being for day display, whereas the panel 9", 9c, or 91 isfor night display. The hand-lever 16 also turns the cam 27 to con- Vtrolthe distance between the disk 24 on the spindle 23 and the disk (5,traveling up and down on the governor-shaft. As before explained, solong as the limit of speed indicated by the visible indicators is notexceeded the governor-disk G does not contact With the disk 24; but whensaid speed is exceeded in the limits below the red or highest speedattainable then the disk frictionally contacts with the disk 24 and thespindle 23 is rotated. The hammer-lever 25 now rotates and strikes thegong 2O to give an audible signal that the limit of speed has beenexceeded.

Having thus described the nature and object of my invention,\vhat lclaim as new, and desire to secure by Letters Patent, is-

In a deviceof the character described, a series of visible signalsadapted to be displayed singly to indicate visually the limit of speedof the vehicle, a hand-lever `adapted to set said visible signals,a-governor controlled by the speed of the vehicle, a disk adapted to berotated and to be elevated and depressed by the governor, an audiblesignal, a spindle adapted when rotated to operate said audible signal, adisk carried by said spindle and arranged adjacent to the governor-diskand means controlled by the movement of the hand-lever for varying thedistance between the two disks independently of the up-and down movementof the governor-disk.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
